and I will paste Stef’s clarification, because it seems my text was a bit obscure :)

Pharo 6.0 will be with the old process.
        - no bootstrap
        - no git
        - 64 bits

So Pharo 6 will be 64 bits?

Yes!

Thierry

 

        - stabilisation

But in parallel to Pharo 6.0 beta we will start Pharo7.0prealpha.
        - with bootstrap
        - process based on git
The idea is to have some months to get Pharo 70 alpha ready with the new process
when Pharo 60 gets out (or at least to get some cycles)

This is important to remark because is a difference in our way of think: until now pharo is “the image”, now it will be different because there is the possibility of build different images starting from the kernel and bootstrapping other packages.

That going to be even bigger than 64 bit, will make it easy to have Pharo distros :) 

I am very interested into hearing about this in the voice meeting . By the way what time is the meeting ? local time France is fine too.
